Questions about Exam Content?

Exam Advice Write down your name and circle your section Flip through the exam and get a feel for the length of it and the types of questions The programming problems are the last questions on the exam – don’t leave them until the last minute!

Exam Advice Most questions have partial credit You should at least attempt every problem If you don’t know how to do one part of the problem, skip it and do the rest You can use comments instead of code (like “# get user input”) if you know what you want a piece of code to do but not how to do it

Exam Advice After you are done coding the programming problems, try “running” your program with some input and making sure it works the way you think it does If a problem is unclear or you think there is an error on the exam, raise your hand
